Advanced oxidation processes (AOP) are a type of chemical treatment that oxidises organic molecules in wastewater that are difficult to manage biologically and converts them to simple final products.
Features and Advantages:
AOPs hold several advantages in the field of water treatment:
- They can effectively eliminate organic compounds in aqueous phase, rather than collecting or transferring pollutants into another phase.
- Due to the reactivity of ·OH, it reacts with many aqueous pollutants without discriminating. AOPs are therefore applicable in many, if not all, scenarios where many organic contaminants must be removed at the same time.
- Some heavy metals can also be removed in forms of precipitated M(OH)x
- In some AOPs designs, disinfection can also be achieved, which makes these AOPs an integrated solution to some water quality problems.
- Since the complete reduction product of ·OH is H2O, AOPs do not introduce any new hazardous substances into the water
